Do you used Torrent? I think most of us use Torrent to download big file in the net.Torrent is a small file (around few kilobytes) with the suffix .torrent, which contains all the information needed to download a file the torrent was made for. That means it contains file names, their sizes, where to download from and so on. You can get torrents for almost anything on lots of web sites and torrent search engines.

But nowadays most of torrent site need money. It needs you to sign up and pay some money. Can't blame them coz now the cost is very high and risk for them to share the file..
